云南澜沧老厂矿区资源可持续开发利用对策

Resource sustainable exploitation-utilization strategy of the Laochang in Lancang,Yunnan

云南澜沧老厂矿区近年资源勘查取得重大突破,不但传统资源量得到较大幅度的增加,还在深部发现新的中型规模Cu矿体和具大-超大型潜力的斑岩Mo(Cu)矿体,矿山资源危机缓解,矿山发展出现新机。在分析资源现状、资源潜力及其可持续利用的基础上,本文根据矿区矿产资源的地质特征、勘探程度和开发利用难易程度等方面的不同,将其分为传统资源、近期接替资源和中长期接替资源。指出:对传统资源要尽可能增储保产,最大限度延长服务年限;对近期接替资源通过探-采结合,逐步开采利用;对中长期接替资源要加速勘查和综合评价,最终完成资源的安全接替。

Resources exploration of the Laochang mining area,Lancang,has obtained a great breakthrough in recent years,not only increased greatly in traditional resources,but also discovered a new medium-sized Cu deposit and a large-extra large potential porphyry Mo（Cu） deposit in deep.Resource crisis in the mine has been relieved and a new development opportunity has been found.On the basis of analysis to status,potential and sustainable utilization of resources,and according to the geological characteristics,degree of exploration and utilization difficulty of mineral resources in the area,they can be divided into traditional resources,the recent replacement resources and mid-long term replacement resources.The paper also points out that people should protect the traditional resources in storage capacity and extend their service life.Recent replacement resources are expected to explored and used gradually through the combination of exploration and mining.The exploration and comprehensive evaluation on the mid-long term replacement resources should accelerate to take over the safety of resource fully.
